During the use of the pre-coating film laminating machine, occasionally some faults will appear. Let's take a look at how to eliminate some common faults.
 First, the machine does not start: the input wire is not connected, the power cord is reversed, and the voltage is not enough.
 2. Inaccurate temperature measurement: thermocouple, temperature controller. Whether the installation is incorrect and damaged.
 3. The working vacuum cannot come up: the gas path is not open, the hand valve or the solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum gauge is damaged.
 4. The main power switch trips: leakage of the input wires on the top of the heating box, leakage of the distribution box, external wires on the equipment, leakage of the motor, etc.
 Fifth, the suction film is not in place: the vacuum is not enough, the air leakage, the temperature is not enough, the film is too thin, the workpiece is pasted with other materials, the concave depth of the workpiece exceeds the lift of the film, the suction time is too short, the film is not lifted, the distance between the workpiece Too close.
 Sixth, the surface of the workpiece covered by the pre-coating film laminating machine is folded and not smooth or the corners cannot be wrapped: the film is not straightened, the film quality is not good, the workpiece is not polished well, the glue is sprayed too much, and the mold below the workpiece Too low.

 7. Breaking phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
